- Kubernetes Graceful Node Shutdown: StatefulSet Pod stuck in completed
Yes, you are correct If the replicaCount is 1, the manual solution is to delete the pod and let the controller recreate it However, if the node that the -0 pod is on is rebooted and that pod is terminated, the higher-numbered pods may also need to be terminated Not necessarily The challenge arises because your "non-cattle" nodes require special handling during reboots, which doesn't
- Enabling graceful node shutdown on EKS in Kubernetes 1. 21
